Function project_component 

pub fn project_component(
    raw: &RawComponent,
    component_id: ComponentId,
    out_diagnostics: &mut Vec<Diagnostic>,
) -> Component

Project a RawComponent into a fully-typed Component.

component_id is assigned by the orchestrator (1-based, per ComponentId). The returned Component carries an empty terragrunt field (populated in Phase 6) and state_backend = None until either the terraform { backend ... } block extractor or the Terragrunt resolver fills it.

Diagnostics surfaced by the projection (malformed addresses, unsupported shapes) are appended to out_diagnostics.
